US 2020/0288476 A1 · DATA TRANSMISSION METHOD AND DEVICE

Abstract

Disclosed is a data transmission method. The method comprises: reserving a first channel and a second channel, where the first channel is used for transmitting data and the second channel is used for transmitting ACKs; sending data to a receiving end on the first channel that is reserved; receiving an ACK that is sent by the receiving end and corresponds to the data on the second channel that is reserved and determining whether the data needs to be cached based on information carried in the ACK; and if the information carried in the ACK indicates that the receiving end has correctly received the data, clearing the data that is cached by a sending end. Through separate transmission of the data and the ACK, an efficiency problem of the sending end in providing MAC in a wireless system in a condition of a limited cache capacity is resolved.

Dependent claims

A method for transmitting data, the method comprising:

reserving, by a first device, a first channel and a second channel by sending a channel reservation frame to a second device, wherein the channel reservation frame indicates a first duration and a second duration and the first channel is for communicating the data during the first duration and the second channel is for communicating an acknowledgement (ACK) associated with the data during the second duration;
and
in response to successfully reserving the first channel and the second channel:
sending, on the reserved first channel, the data to the second device during the first duration;
and
receiving, on the reserved second channel, the ACK associated with the data from the second device during the second duration.

A method for transmitting data, the method comprising:

reserving, by a second device, a first channel and a second channel in response to receiving a channel reservation frame from a first device, wherein the channel reservation frame indicates a first duration and a second duration and the first channel is for communicating the data during the first duration and the second channel is for communicating an acknowledgement (ACK) associated with the data during the second duration;
and
in response to successfully reserving the first channel and the second channel:
receiving, by the second device, the data from the first device on the reserved first channel during the first duration;
and
receiving, by the second device, during the second duration and on the reserved second channel, the ACK associated with the data sent by the first device.

3 more elements

A first device comprising a processor and a non-transitory computer-readable medium having processor-executable instructions stored thereon, the processor-executable instructions, when executed by the processor, facilitating the following:

reserving a first channel and a second channel by sending a channel reservation frame to a second device, wherein the channel reservation frame indicates a first duration and a second duration and the first channel is for data during the first duration and the second channel is for an acknowledgement (ACK) associated with the data during the second duration;
in response to successfully reserving the first channel and the second channel:
sending, on the reserved first channel, the data to the second device during the first duration;
and
receiving, on the reserved second channel, the ACK associated with the data from the second device during the second duration.
